What if Britain built four CVA-01 carriers, the Invincible class, and eight Fearless-class landing platform docks?
Short answerThe Royal Navy could remain the second strongest fleet and give the United States a much more capable burden-sharing ally.
NotesKeeping four CVA-01 carriers and then building the Invincible class to replace older light carriers would preserve a much larger fixed-wing and anti-submarine aviation force. Eight Fearless-class landing platform docks would add a matching amphibious capacity. The resulting Royal Navy could remain the world's second most powerful fleet rather than contract around a few isolated high-end ships. Washington might initially worry about Britain's ability to act independently, but over time the United States would gain an ally capable of carrying a larger share of global maritime commitments.
